How Often Should the Four-Matching Parts Be Replaced?
2 Answers
Four-matching parts refer to the piston, piston rings, piston pin, and cylinder liner. They are typically replaced every two years. Regular vehicle maintenance is also essential. Below is a detailed introduction to vehicle maintenance: Overview: Vehicle maintenance refers to the preventive work of regularly inspecting, cleaning, supplying, lubricating, adjusting, or replacing certain parts of the vehicle, also known as vehicle servicing. Currently, vehicle maintenance mainly includes the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, and other maintenance scopes. Purpose: The goal of vehicle maintenance is to keep the vehicle clean and in normal technical condition, eliminate potential hazards, prevent failures, slow down the deterioration process, and extend the service life.
As a seasoned driver with over 20 years of experience, I'd like to talk about four-piece set replacement. Actually, there's no fixed interval for changing it because it's not a maintenance item—it's only involved during major engine overhauls. The four-piece set mainly includes pistons, piston rings, cylinder liners, etc., which are core engine components. Under normal usage, inspection is typically needed every 100,000 to 150,000 kilometers, but the replacement interval entirely depends on daily driving conditions. For example, if you're stuck in city traffic every day like me, causing greater engine wear, you might need to pay attention after just 8 years. If you mostly drive long distances on good roads, it could last over a decade without issues. The key is watching for symptoms: if you notice excessive oil consumption, blue smoke from the exhaust, reduced power, or increased noise, get it checked immediately. Delaying could lead to bigger losses—my previous car suffered a blown engine due to neglect, costing 8,000 RMB to repair. Now I keep detailed maintenance records and have professionals evaluate it every 50,000 kilometers. In short, don't wait for a breakdown—prioritizing safety also saves money.
